Cabbage Tree Bay Aquatic Reserve is a fully protected no-take zone on Sydney's Northern Beaches. The marine life here is extraordinary — blue gropers swim up to you, cuttlefish hover in the shallows, and sea turtles feast on the sea grass.
An entry from South Manly makes it one of Sydney's most popular swim spots. Walk in off the sand at Shelly Beach and you're surrounded by hundreds of species within minutes.
